ORIENTAL
MACKEREL
(Scomber japonicus)
Order: Percomorphi
Sub-order: Rhegnopteri
Series: Scombriformes
Family: Scombridae
The Oriental mackerel is found principally in
Korean waters. It is very closely related to mack-
erel found in other locations but some ichthyologists
are inclined to believe it to be a distinct species. A
famous authority tells us that S. japonicus spawns
in May and that the fry grow rapidly, feeding on
the fry of other fish. They are adult when about
14 inches in length, a 23 inch fish being considered
very large and rare. As a rule none of the genus
Scomber grow to large size and two pounds is
about the largest ordinarily caught. The financial
welfare of many fishermen depends upon the ap-
parently inexhaustible supply of
mackerel. We are told that in one
haul with a purse seine 260,000 mack-
erel were taken and that it is not un-
common for as many as two millions of mackerel to
be landed at one port in one day. Scomber japonicus
is closely related to the Pacific mackerel (Pneuma-
tophorus diego) and also to the Atlantic species
(Scomber scombrus).
